Description

Two moving electric switch with haptic effect

Background technology

The present invention relates to electric switch, it allows at least two electric switch paths to be set up in succession by activation part, and the user promotes described activation part by applying a pressure.

This control system allows the user to apply the pressure of an initial mild in succession, setting up the first switch path, and then, applies big pressure, to set up the second electric switch path.

In the phase I, the user awares certain elastic resistance, and then, when setting up the second switch path, the sense of touch that switch gives the user is that this switch path is set up.

Sense of touch obtains by means of the triggering element of elastically deformable, and described triggering element for example is a dome shape body, and described triggering element applied pressure is caused state mutation, can set up an electric switch path on the one hand, and can provide described sense of touch on the other hand.

This two moving or double voltage type switch is used for many electronic devices, especially for camera or video camera, wherein, the button of the switch that the control shutter discharges is handled by two stages with axial stroke, thereby, for example in the phase I, carry out " automatic focus ", then, in second stage, carry out the actual release of shutter and/or the record of digital document.

Other application---wherein needs to set up in succession two electric switch paths so that for example set up two continuous signals---and comprises being used to control the button that affirmation is controlled in selection then, perhaps comprises being used to control the button that this function executing is controlled in function starting then.

Background technology

For this what is called " two moving " or " double voltage type " switch have proposed different designs.

Document US-A-4659881 proposes a kind of switch, and it has two coaxial superimposed conduction dome shape bodies, and it works as movable contact, and function is started in control earlier one in succession, controls one then and triggers function.

Second solution is addressed in document US-A-5898147, and it uses two triggering elements to work as movable contact, and each triggers element and has four radial arms, and it gives stacked and interlocking.

The 3rd document US-A-4359614 also proposes a kind of switch, and it has dome shape body, and described dome shape body down forms a movable contact, and the contact crosshead of an elastically deformable is housed on its top.

In this similar document, all have at least one and " fix " dome shape body down, it is bearing on the supporting member of a carrying fixed contact by its annular lower limb, document US-A-5564560 also can mention, in order to set up the first switch path, the document is used a flexible circuit, its conductive region is bearing on the end face of dome shape body together with a start axial pusher, described axial pusher has an active contacting plate, it sets up one first switch path between these conductive regions after finishing first actuating travel.

Document US-A-6498312 proposes a kind of whole " two " and triggers element, and it has two groups of radial arms, and in this solution, this triggers and twice distortion in succession of mobilizable contact element, to set up two circuit switched.

All these solutions because it uses two stacked dome shape bodies or a plurality of stacked contact assembly, perhaps require to exceed electrically contacting outside the dome shape body localized area particularly along occupying a large amount of especially spaces as rotation axis.

When using two dome shape bodies or similarity piece, the precision adjustment of switch---control that especially is used as power---is complicated especially.

Document US-A-4385218 proposes a kind of switch, it has one and forms single dome shape body and movable contact element that triggers element, described movable contact element is out of shape at two successive stages, between fixing perimeter contact, to set up one first electric switch path in succession, then, distortion once more is to set up one second electric switch path between these perimeter contact and a fixed center contact.

In this embodiment, originally single triggering element or dome shape body are bearing on the bottom of the housing that holds it, most of intrinsic problem is resolved at least in part, and still, the industrial production of the dome shape body that this shape is special is very complicated, because described dome shape body especially has a cutting part, make it to be divided at least two dwell of cams, and make it to carry out twice distortion, simultaneously, this dome shape body bears large deformation, and its operating period falls short of.

First embodiment

Fig. 1 to 4 illustrates two moving electric switches 10, here, two moving electric switches 10 illustrate by the form of the mode that hints without limits with a self-contained unit, and it is especially for being fixed in a printed circuit board (PCB) 12 by welding manner, and accompanying drawing illustrates four parts of described two moving electric switches 10.

In general, electric switch 10 carries out symmetric design with respect to vertical vertical centering control plane P VML shown in Figure 4.

The known ground in this field, switch 10 is made up of a pedestal or housing 14 basically, and it has the general shape of a right angle parallelepiped, and makes by the mode of electric insulation plastic moulding.

Housing 14 is especially limited by its upper horizontal plane 16 and lower horizontal plane 18 thereof.

Housing 14 part in the central has a chamber 20, and described chamber 20 makes progress vertical openings in end face 16, and is defined by the bottom 22 of a flat horizontal and the vertical sidewall 23 of a concave cylindrical shape.

In the rigging position of assembly, chamber 20 accommodates mobilizable contact element 26 of bending at least in part, and actuation element or pusher 28 vertically extend above the plane of end face 16 here.

Chamber 20 also accommodates a last dome shape body 24 with known domed overall shape, the described dome shape body 24 of going up is for having the last dome shape body of state mutation, the described dome shape body 24 gone up is put between activation part and mobilizable contact element 26 between vertical, when the second switch path is set up, the sense of touch that described upward dome shape body 24 provides as the state mutation result, but from the conductivity viewpoint, described upward dome shape body 24 does not participate in the foundation in electric switch path.With regard to this respect, dome shape body 24 needn't be made of metal.

At the rigging position of assembly, switch is coated with a closing seam diaphragm 21, and it guarantees the sealing on the top of chamber 20, and pusher 28 is fixed to described seal membrane 21 by adhesive.

According to known technology, housing 14 is around otch shown in Figure 7 and compound molded the forming of bonding jumper bending, to form fixed contact and relevant binding post.

Therefore, switch 10 has one first and one second

fixing perimeter contact

30A and 30B in the bottom of chamber 20, each fixing perimeter contact all independently is electrically connected with the outside by relevant binding post 32A, a 32B, described

binding post

32A, 32B is designed to be able to is electrically connected with a corresponding circuit, and described circuit relatively forms by the top part with printed circuit board (PCB) 12.

Each fixing

perimeter contact

30A, 30B is arranged to approach the vertical sidewall 23 of chamber 20, and the shape that is a disk, here disk is formed vertically to protrude by following manner: extend above the plane on the upper water plane that its upper level scope of

freedom

34A, 34B form in the bottom 22 by chamber 20.

Equally, described switch has one the 3rd fixing center contact 36, its shared fixed contact for being electrically connected with other two electric connecting

terminals

38A and 38B, described electric connecting

terminals

38A and 38B are used to be connected to the corresponding conducting wire on the printed circuit board (PCB) 12 again.

Also by the form manufacturing of a disk, its end face 40 extends in certain height with respect to described flat bottom 22 on a horizontal plane fixing center contact 36, and described height is a little less than the height of end face 34A and 34B.

One cavity 42 is arranged in the bottom of chamber 20, is used for locating mobilizable contact element 26 of described bending angledly, and described cavity 42 extends in the recess downward vertically, and is undertaken Unitarily molded by ambroin.

Cavity 42 is positioned between two fixed contact 30A and the 30B with respect to plane P VML centering.

The bottom of chamber 20 and described cavity 42 vertically relatively have a supporting step 19 that is used for mobilizable contact element 26, and described supporting step 19 upwards vertically protrudes and carries out Unitarily molded forming with ambroin.

Supporting step 19 is own with respect to plane P VML centering, and its upper level plane 17 is on the identical plane with perimeter contact 30A that fixes and end face 34A and the 34B of 30B.

Chamber 20 is admitted mobilizable contact element 26, and makes it to be positioned at the initial tranquillization position of lifting.

Particularly as illustrated in Figures 5 and 6, mobilizable contact element 26 integral body have the form about a dome shape body of string of a musical instrument bending.

Or rather, before bending or bending, mobilizable contact element 26 as going up dome shape body 24, is the shape of the spherical crown with continuous structure here, mobilizable contact element 26 is for example formed by metal bending, and is limited by circular periphery edge, a bottom 54 in its underpart part.

In the non-bending design of its routine, and as the conventional electric switch that is used to have the single switch path, the all points at lower periphery edge 54 are on identical plane, and belong to a public bottom surface, in other words, they extend on a common plane, described common plane can substantially be at its whole peripheral upper support on a horizontal plane, this support region generally has at least one peripheral stationary electrical contacts.

Mobilizable contact element 26 also has the last middle body of a dome shape, and it is limited by a convex end face 27.

On this upper surface 27 of central dome shape part, activation part or pusher 28 are by last triggering dome shape body 24 indirectly-actings.

Mobilizable contact element 26 bends in such a way about a string of a musical instrument or folding line C at its stable quiescent condition and forms: the have a few that belongs to the part of outer peripheral edge 54 is setovered downward vertically with respect to the general layout that edge 54 extends, and the described central axis that radially is positioned at described string of a musical instrument C of having a few is relative.Therefore, according to the present invention, mobilizable contact element 26 has a bending part 51, and the bottom free end of described bending part 51 comes down to a bit here, and described bottom free end is setovered downward vertically with respect to the plane of lower limb.

Therefore, shown in Fig. 5 or 6, mobilizable contact element 26 has the end points 52 that the part bending down is divided, and described end points 52 is the minimum point with respect to the plane perpendicular positioning of lower limb 54.

Stable tranquillization position when mobilizable contact element 26 is positioned in the chamber 20, point 52 is received within the bottom of cavity 42, is bearing on the bottom 43 of this cavity 42.

Therefore, except that its supporting functions, the point 52 that cooperates with cavity 42 makes mobilizable contact element 26 carry out the location of certain angle about central axis VA.

In this stable initial tranquillization position, being bearing on the end face 17 of step 19 at diametrically opposite point of lower limb 54 with point 52.

Therefore, mobilizable contact element 26 is positioned in the chamber 20 at an angle with a gap, especially, so that can not in housing, rotate, and when its strain, its motion is limited to distortion and banking motion, and this will be described below.

The size of mobilizable contact element 26 and particularly external diameter are such: described mobilizable contact element 26 accommodates at least in part and is positioned in the chamber 20.

As shown in Figure 5, the point of the lower limb 54 of mobilizable contact element 26---point that comprises its folded end---does not contact end face 34A and the 34B of fixing

perimeter contact

30A and 30B, does not support thereon, thereby do not electrically contact with it yet.

According to known master-plan, particularly in order to produce haptic effect when mobilizable contact element 26 flexibly is out of shape by the state mutation mode, mobilizable contact element 26 conducts electricity on the concave surface at least within it.

As shown in Figure 5, tranquillization position at switch, in other words, when the user does not apply any active force to start pusher 28, the lower limb 54 of mobilizable contact element 26 is with respect to angle [alpha] of horizontal plane inclination of

face

17,34A and 34B, and its lower limb and end face 34A described two fixing

perimeter contact

30A and 30B and the part that 34B relatively extends vertically are positioned at the top of these end faces 34A and 34B, in other words, between mobilizable contact element 26 and perimeter contact 30A that fixes and 30B, do not electrically contact.

When the user by pusher 28 by the vertical direction of arrow F in Fig. 5 on to mobilizable contact element 26 on convex surface 27 when applying active force (this active force centers basically on vertical axis VA), first thrust that puts on mobilizable contact element 26 by last triggering dome shape body 24 causes described mobilizable contact element 26 strain first, described mobilizable contact element 26 integral body are about the string of a musical instrument or folding line C and resist its intrinsic flexibly distortion, with " recovery " similar " routine " shape of shape with last triggering dome shape body 24, in this shape, lower limb have a few and all on identical bottom surface, extend basically, and, as the result of mobilizable contact element 26 effects of run-off the straight simultaneously, continuous lower limb is the level of state.

After finishing this and being out of shape for the first time, mobilizable contact element 26 is in then and dips, dip at this, the corresponding points of the bottom conductive edge of mobilizable contact element 26 rest on coplane end face 34A, the 34B of fixing

perimeter contact

30A and 30B simultaneously by the mode that electrically contacts.

Therefore, mobilizable contact element 26 is shifted to the switching position of final reduction from the initial tranquillization position of lifting shown in Figure 5, switching position in this reduction, the circular periphery edge 54 of mobilizable contact element 26 rests on two first fixing perimeter contact 30A, the 30B, sets up first TURP and changes the path---thus between

terminal

32A and 32B---so that between these contacts.

After the first start stage finished, mobilizable contact element 26 is " flat " basically, and is positioned at " routine " position, in this position, it is bearing on the horizontal plane by circumferential annular zone, its underpart or lower limb, so that make it to carry out " routine " state mutation then.

Then, the user is continuously applied thrust with bigger strength in the direction of arrow F, makes in known manner to trigger

dome shape body

24 and 26 while of mobilizable contact element strain, and makes their state mutations.After this was out of shape end for the second time, the bottom conducting surface of the middle body of mobilizable contact element 26 electrically contacted with the end face 40 of the center contact 36 of fixing.

Then, except that the user is produced the sense of touch, in other words this distortion, between

binding post

38A, 38B and 32A, 32B, sets up the second electric switch path between fixing center contact 36 and perimeter contact 30A that fixes and 30B.

As embodiment, equal 2 millimeters one triggering element 24, the first actuating travels and approximate 0.1 millimeter greatly for diameter, active force is 1 newton, and second actuating travel approximates 0.2 millimeter greatly, is used as power to equal 2.5 newton.

As embodiment, for this dome shape body that diameter equals 2 millimeters, the distance at the center of mobilizable contact element 26 of the string of a musical instrument or folding line C and bending is about 0.7 millimeter.

Adopt the affix triggering dome shape body 24 of conventional non-bending design to make it and to increase different elastic restoring force numerical value and sense of touch by known manner, but, affix triggers the upper position of dome shape body 24, and---it is bearing on the end face of mobilizable contact element 26 of bending---prevents to contact or cooperation with any of described fixed contact, thus, the upper position of affix triggering dome shape body 24 does not participate in the foundation in electric switch path.

As embodiment, different fixed contacts can directly belong to a printed circuit board (PCB) rigidity or flexible property.

The present invention also is not limited to two fixing perimeter contact.In fact, for example, can arrange one the 3rd fixed contact (not shown), described the 3rd fixed contact is not electrically connected with two fixing

perimeter contact

30A and 30B, described the 3rd fixed contact is arranged in the bottom 43 of cavity 42, and described the 3rd fixed contact is connected to the outside by a relevant binding post, and described binding post is designed to be electrically connected with corresponding circuit, and the top part of corresponding circuit and described printed circuit board (PCB) 12 relatively forms.

Therefore, mobilizable contact element 26 permanently electrically contacts with the 3rd stationary electrical contacts---and it does not belong to two first switch paths, and, after second deformation stage finished, mobilizable contact element 26 was set up two electric switch paths simultaneously: the Third Road footpath between above-mentioned second path and supplementary contact that should be fixing and the fixing center contact 36.

Point 52 under mobilizable contact element location at an angle also can be can't help carries out, and for example undertaken by an angle location tongue piece, described angle location tongue piece can by cutting with bending whole formation, and it is received within for this reason and in the cavity or otch arranged.

Second embodiment

Second embodiment shown in Fig. 8 to 11 is described now, and the difference of itself and first embodiment only is the design of mobilizable contact element 26.

Here, mobilizable contact element 26 is the shape of a metallic plate, and it is cut and is crooked, and has a continuous structure, and this continuous structure has the planar bottom surface 54 of conduction.

Form mobilizable contact element 26 plate general shape fully and the indent profile complementation of chamber 20.

At its rear portion, and look the left-hand side of seeing at Fig. 9 to 11, the plate that forms described mobilizable contact element 26 has a periphery edge of round cross section, and it is similar to the mobilizable contact element 26 among first embodiment.

In stable initial tranquillization position, the point of this lower limb is bearing on the end face 17 of step 19.

With this left-hand side rear portion point on diametrically opposite ground, the plate that forms described mobilizable contact element 26 has a tongue piece 51, tongue piece 51 be cut form and downward vertically the bending, thereby extension below the general layout of plate.

Bending tongue piece 51 is shaped in the mode of its free end by directed downward vertically convex body, thereby defines a horizontal line 52, is used to be bearing in the face 43 of housing 42 bottoms, and the free end of bending tongue piece 51 is received within the housing 42.

Bending tongue piece 51---it is used to support and the plate of the mobilizable contact element 26 of the described formation of angle location---extends between two

flange

53A and 53B, each flange is all a movable contact flange, after described movable contact flange can be finished in the tilt displacement stage of the deformation stage of tongue piece 51 and movable contact plate 26, electrically contact with end face 34A, the 34B of the perimeter contact 30A that is relatively fixed, 30B.

The central area 27 of plate---it is similar to the central area of the top convex surface 27 of mobilizable contact element 26 among first embodiment---is an entity part, and its underpart conducting surface relatively extends with the end face 40 of the center contact 36 of fixing.

Top is triggered dome shape body 24---they are edge limited by a circle or circular periphery---and permanently is bearing on the respective regions of each flange among two flange 53A and the 53B, and permanently is bearing on the respective regions of the plate that forms mobilizable contact element 26.

Activation part 28 triggers the plate indirectly-acting of 24 pairs of mobilizable contact elements 26 of described formation of dome shape body by top, and it is much bigger that the described formation of ratio of rigidity that dome shape body 24 is triggered on top has the rigidity of plate of movable contact element 26 of deformability tongue piece 51.

In the first start stage, described activation part 28 and described dome shape body 24 cause described tongue piece 51 distortion, the plate of the mobilizable contact element 26 of described formation are tilted, to set up the first switch path by angle [alpha].

Finally dip at this of plate 26, the circular periphery edge that element 24 is triggered on top makes plate 26 remain on the horizontal plane bearing position.

The adjection that triggers element 24 central authorities makes the state mutation that triggers element 24, therefore, the relative central area 27 that the middle body of triggering element 24 clashes into the plate of the mobilizable contact element 26 of described formation then, described contact element 26 is out of shape, thereby, after very short stroke, described contact element 26 is bearing on the end face 40 of fixing center contact 36 by the mode that electrically contacts, thereby sets up the second electric switch path.

Because the plate that forms mobilizable contact element 26 is as among first embodiment, there are not otch or central recess, so have extra high rigidity, described high rigidity is particular importance, this makes that producing small-sized switch becomes possibility, when the overall diameter with triggering dome shape body 24 of mobilizable contact element 26 is less than or equal to 2 millimeters, especially true.

The design of the invention described above is in vertical direction and all occupy a spot of especially space in a lateral direction, and make it to become possibility: by mode with identical " a bottom part ", in other words, by having an identical housing or the mode of pedestal 14, manufacture order dynamic formula electric switch, in chamber 20, place a routine triggering dome shape body similar with triggering dome shape body 24, then, originally described triggering dome shape body rests in the electric contact state by its lower limb and two fixing

perimeter contact

30A and 30B, perhaps produce electric switch of the present invention, it has two electric switch paths, and these two electric switch paths use mobilizable contact element 26 of the dome shape bodily form of a bending to set up in succession.

The present invention is not limited to the switch of being handled by a vertical pusher, but also can be applicable to have the situation of transmitting the lateral control of motor function along vertical axis.
